ships.

As is well known, owing tothe radiation from the sun at d ay-time'andthe heatingl of the gas caused'thereby, the air-ship has a greaterbuoyancy and therefore tends to In consequence thereof it becomesnecessary lto drive the airship down by the head in order to keep it atthe same height. By doing so a dynamic downwards pressure is obtainedand unnecessary losses of gases l5 are ob`viated.` The conditionsarising at night are contrary to those explained above.

In orden-now, to do awa-y as far as possible with the disagreeabledifferences between the trim of the airshi at day and at night,

a novel distribution o the cabins designed to take up the passengers isresorted to. To this end the, pasengers sleeping-rooms are disposed,according to the present invention, relatively to the passenger rooms tohe used at daytime in such a manner that during day-time the bow andduring the night the stern is down.

In the drawings aixed to this specification and forming partthereof, anairship embodying my inventionk is illustrated by way of example.

. The gas cell a carries a passenger car directly fixed to it, said carcomprising a room I) to be used during day-time vand a sleepingrooln orrooms 0 disposed further astern.

l. In an airship in combination a. passenger room for day sojourn and apassenger room for nights rest, said rooms being so arranged in relationto each other that a passenger going to bed at night will by thisdislocation of his Weight cause an upward Weight moment in the shipstrim, thereby working towards compensation for the difference ofbuoyancy between day and night conditions. i

2. Passenger accommodations in an airship comprising a space for daytime sojourn of a passenger and another space for his nights rest, saidsecond space being situated astcrn from said first space, therebyproviding for automatic shifting of the pas'l sengers Weight atnightfall. and at daybreak and counteracting theinfluence of day andnight conditions on the airships buoyancy. In testimony whereof I affixmy signature.

PAUL JAR-AY.
